The world is watching as Bruce Jenner, 65, transitions into a woman, and on April 24, for the first time, all will finally be revealed about the massive decision.

Bruce Jenner’s 20/20 Interview Preview: Fears For His Family

With six kids, four step-kids and three ex-wives, Bruce knows his sex change is affecting many more people than just himself.

“They’re the only ones I’m concerned with,” he reveals to Diane of his family members, which include teenage daughters Kendall and Kylie Jenner, in a preview for the tell-all. “I can’t let myself hurt them.”

We also get a full-face view of Bruce, who adds of his journey, “It made me who I am.”

Even though ABC has now released three clips for the upcoming exclusive, very little footage has been revealed. “My whole life has been getting me ready for this,” Bruce said, simply, in another preview.

To tease the 20/20 special, the network added that we will learn about “the journey, the decisions and the future,” so there’s definitely a WHOLE lot we’re going to find out when this full episode airs! And with the interview spanning two hours, we can definitely expect Bruce to put it all out there.

Make sure to tune into ABC at 9pm on April 24 to see the full thing.
